Basically, nothing. The critters will break through anything and attach
themselves to your prop. Frequent use ast high speed does help, though.
The infestation will mostly be around the hub then.

What I have found that works somewhat is a large donut-type zinc
installed tight-flush against the propeller hub. The zinc seems to
provide a zone of protection a few inches on either side of the prop
hub. You still get the critters on the blades but not in as great
numbers as you would without the zinc.

Prop Speed works great. And is well worth the extra cost.
